SPECIFICATION forming part of Letters Patent No. 780,099, dated January17, 1905. Application iiled April 4, 1904. Serial No. 201,545.

T0 coll when?, it may concern:

Be it known that I, JAMns ANDREW Goon- Nnin a citizen of the UnitedStates, residing at Rockyford, in the county of Otero and State ofColorado, have invented a new and useful Water-Elevator, of which thefollowing' is a specification. y

This invention relates to that class of waterelevators which are alsoknown as chainpumps, and it has among its objects to provide apump-cylinder adapted to cooperate with peeuliarly-constructed bucketsmounted upon an endless chain, so that water elevated through thecylinderl by the action of the pump buckets or lpistons may be raised toany desired height through an ordinary conductl ing-pipe of largerdiameter than the pistons, thereby saving wear upon the latter andinsuring a perfectly steady action of the device.

Further objects of the invention are to provide a device of the classreferred to which shall possess superior advantages in point ofsimplicity, durability, and g'eneral efficiency; and with these andother ends in view, which will readily appear as the nature of theinvention becomes better understood, the same consists in the improvedconstruction, arrangement, and combination of parts, which will behereinafter fully described, and particularly pointed out in the claims.

ln the accompanying drawings, Figure 1 is a vertical sectional view ofmy improved water-elevator, showing the same applied in operativeposition. Fig. Qis a vertical transverse sectional view taken on theline 2 2 `in Fig. 1. Fig. 3 is a top plan view, enlarged, of one of thepistons or pump-buckets. Fig. 4 is a sectional view ofthe same, taken onthe line 44in Fig. 3. Fig. 5 is a vertical sectional view illustrating amodified construetion of the piston or pump-bucket. Fig. 6 is a verticalsectional view illustrating another modification.

Corresponding parts in the several iigures are indicated by similarnumerals of reference.

rlhe member 1, which l designate the cylinder of my improved pump, iscylindrical throughout the greater part of its length and is providedwith a smoothly-iinished bore. The lower end of the cylinder has afunnelshaped enlargement 2, terminating in an annular i'lange 3, andtheupper end of the cylinder has a flaring portion 4, terminating in anannular .flange 5.

6 designates a casing which is suspended or supported in the bottom ofthe well, said casingl being provided in one side thereof with anopening i?, covered by a screen 8, for the admission of water. Thecasing 6 is provided with slots 6", forming bearings for a transverseshaft 9, carrying a sprocket-Wheel 10, the upper side of the casingbeing' slotted. for the accommodation of the sprocket-wheel as well asfor the down and up going' pistons, the opening' for the down-goingpiston being indicated at 11 and that for the rip-going piston at 12.'lhe latter opening is of a diameter equal to the expanded lower end ofthe pump-cyliiuler, which is secured in alinement with said openings bymeans of bolts or fastening' members 13.

Suitably connected with the flange at the upper end of the pump-cylinderis a conducting-pipe 14, which is of an interior diameter slightlyexceeding that of the pump-cylinder, so that the pump-pistons may travelupwardly through said conducting-pipe without frictional contact withthe walls thereof. Said conc'luctingqbipe may be composed of any desirednumber of lengths or sections suitably connected with each other and itmay be constructed of any suitable material. Above the ground theconducting-pipe 14 is provided with a laterally-extending outlet 15, andthe top section of the pipe, above the outlet 15, is composed of twovertically-divided members 16, having' lugs 17 :for the reception ofconnecting' bolts or members 18, and provided with brackets 19,aii'ording bearings for a driven shaft 20, carrying a sprocket-wheel 21.

22 designates the pump-chain, which is supported upon thesproeket-wheels 21 and 10, said chain being made up of iat links 23,engaging the sprocket-wheels and provided at intervals with buckets orpistons 24. The latter are preferably cast of iron, although with-` inthe limits of my invention any suitable material may be employed, andsaid pistons consist each of a circular disk of suitable dimensionsprovided on its upper and under sides IOC) With approximatelysemicircular bails and 25, crossing each other at right angles andprovided at their points of intersection with means, such as a hook 25hand a link 25C, for connection with the chain-links. Each of thesepistons is provided with a circumferential g'roove 26, in which isplaced a packingring 2T of resilient metal and having' overlapping ends,said packing-ring being in the main of the character ordinarily employedin piston construction to provide a leak-proof joint between the pistonand the cylinder in Which it works. The pistons 24 are spaced apart uponthe chain 22 a distance equal to the periphery of the sprocket-wheels,each one of which is provided with a peripheral recess 28 to accommodatesaid pistons during the operation of the device, as will be readilyunderstood. The cylindrical bore of the cylinder is also to be of alength at least equal to the distance from center to center of proximatebuckets upon the endless chain in order that when one piston passes overthe upper end of the cylinder another piston shall simultaneously beentering' the lower end of the cylinder, thereby preventing water frombacking into the well.

The operation and advantages of this invention will be readilyunderstood from the foregoing description, taken in connection with thedrawings hereto annexed.

It will be observed that by this invention water will be positivelyforced in an upward direction through the cylinder l by the action ofthe successive pistons and also that the said pistons have no frictionalcontact with the conducting-pipe, thereby effecting' a great saving inpower, while the effectiveness of the operation is not lessened. Thegeneral construction of the pump is of such a nature as to insurepermanency and long life to the parts, and there is no danger of thepump getting out of working order. Under ordinary circumstances a columnof water will always fill the conducting-tube, thus causing' the waterto flow as soon as the operation of the pump is begun. l/Vhen in coldweather it shall be desired to return the column of water to the Well inorder to avoid freezing,'this may be easily effected by operating thepump reversely, as will be readily understood, the upper end of thecylinder being purposely expanded in order to permit such operation totake place.

Under the preferred construction of the pump-piston (illustrated inFigs. l, 2, 3, and 4) each piston-plate, with its yokes or bails 25 and25n and the connecting means 25b and 25, has been shown as cast orformed in a single piece. In Fig. 5 has been illustrated a modifiedconstruction, whereby the connecting means, shown as consisting of ahook 30 and a ring or link 31, have been provided with screw-threadedshanks 32, extending through the bails of the piston at their points ofintersection, where perforations 33 are provided for the passage of saidshanks, said connecting members being secured in position by means ofnuts 34 upon their threaded shanks. Still another modification(illustrated in Fig. 6) shows the crossed yokes or bails 25 25L as beingformed separate from the piston-plate 24, upon the Lipper and lowersides of which the crossed bails are caused to abut, said bails beingconnected and tightened upon the piston-plate by means of a bolt 35,having at one end a hook member 36 and at its other end a link 37, whichlatter also serves as a tightening-nut. lVhen this bolt is used, it isobviously necessary to perforate the piston-disk for the passagethereof. I do not deem it necessary, however, to pack this perforation,inasmuch as the bolt ymay be made to fit quite snugly therein, and itmay even be found de` sirable to leave a slight opening or vent throughwhich water may leak back into the well instead of being left standingin the Welltube. The yokes or bails,which form part of the piston, serveto guide the piston-plate and to steady the movement thereof, thuspromoting the efficiency of the pump. These simple modifications willsuggest many others which may be resorted to within the scope of theinvention, and I desire it to be understood that I reserve to myself theright to such changes and modifications as may be used Without'departing from the spirit of the invention or sacrificing any of theadvantages of the same.

Having thus described my invention, I claim- 1. In a water-elevator, acasing, a sprocketwheel supported in said casing, the latter beingprovided with openings for the accommodation of said sprocket-wheel andfor downgoing and up-going pistons, a cylinder having fiaring iiangedends, said cylinder being supported upon the casing in alinement withthe opening for the up-going piston members, a conducting-pipe connectedwith the upper end of the cylinder, said conducting-pipe being of aninterior diameter' greater than that of the bore of the cylinder, alateral exit upon said conducting-pipe, separable top members for thelatter, having supporting-brackets, a shaft iournaled in said brackets,a sprocket- Wheel upon said shaft, an endless chain supported upon theupper and lower sprocketwheels, piston members carried by said chain,and packing-rings upon said piston members, the sprocket-wheels beingprovided with recesses for the accommodation of said piston members.
